M400 concrete is a high—strength grade designed for particularly demanding structures experiencing significant mechanical and dynamic loads. It is characterized by high density, resistance to aggressive environments and minimal shrinkage, which makes it a reliable choice for technically demanding facilities.
This concrete is widely used in the construction of bridges, overpasses, bank vaults, industrial floors, columns, slabs and other structures where increased strength and wear resistance are required. It is also used in hydraulic structures and monolithic construction of multi-storey buildings.
Concrete M400 retains its characteristics in conditions of temperature fluctuations, high humidity and in contact with a chemically active medium. It provides excellent adhesion to fittings and has a long service life
